Hi,

     I'm working on TDA2x,and visionsdk02.10.00 i used.Any source inside for developing Radar sensor?Liked read radar's data  with DCAN,and output with GPIO.

very thanks.

    No there is nothing in vision sdk 2.10 for this. Can you please explain how radar is interfaced to TDA2x for you? and which radar chip is this (TI or someone else)?

    hi,Yogesh
    I use a radar come from Delphi,which have a DCAN interface(500k baudrate).Actually,i want to read Radar's data with DCAN 20 times in a second.
    thanks.

    I dont know if DCAN is the right interface for this. As I said vision sdk by default doesnt have solution for this. You may have to look at examples\tda2xx\src\modules\dcan to see how rx, tx can work and thn build an application on top of that.

    Thanks Yogesh,

    I have abled to communicate with the sensor with DCAN now. Seems that DCAN function is running on ipu1_1 core. Can u decribe the detail of DCAN. I want to get the Dcan data and sending to ipu1_0 core.How can i do it? IPC_IN and IPC_OUT?

    thanks.

    I think if you compile it for ipu1_0 it should work straight away.

    In vision sdk 2.11 we have it in ipu1_0, vision_sdk\examples\tda2xx\src\modules\dcan\SRC_FILES.MK would look like this

    SRCDIR += $(vision_sdk_PATH)/examples/tda2xx/src/modules/dcan

    DCAN_SRCS = \
      utils_dcan.c \
      system_dcan.c


    SRCS_ipu1_0 += $(DCAN_SRCS)

    Yogesh,

    Thanks your reply in time. Yes, Then i can get the DCAN data from ipu1_0 core after i follow your method.

    If i want to share this Dcan data with other core like DSP or A15,does there have a easy way to do this. Or i have to use the link of ipc_in and ipc_out?
    thanks!

    Oh Yes for moving data to other core you need to use IPC_OUT and IPC_IN but you need to see how to feed it to IPC_OUT first.

    I will say you can have your own DCAN capture/rx link or modify NullSrc to do this and then feed data to IPC_OUT on ipu1_0. Please see if System Buffer types supported by vision sdk are sufficient for handling data in your case when it is moved within SOC (metadata should work I guess) or else you may have add that too. Vision SDK is mainly has System Buffers that are suitable to contain video content e.g. yuv buffers / metadata / composite frames / bitstream etc. You can look at system_buffer.h for more details.
